Abstract
A battery pack that does not increase contact resistance when an impact is applied to a bare cell and a protection circuit module. The battery pack includes: a bare cell having a surface on which at least one coupling groove is formed; a protection circuit module electrically connected to the bare cell; at least one coupling member having one end coupled to the protection circuit module and another end in which at least one coupling hole corresponding to the at least one coupling groove of the bare cell is formed, and tightly adhered to the bare cell; at least one screw bolt coupled to the at least one coupling groove through the at least one coupling hole; and at least one space formed in an opening part of the at least one coupling groove, having a diameter greater than that of the coupling groove. Therefore, the battery pack does not increase the contact resistance between the bare cell and the protection circuit module against an external impact.
